Excellent alarm clock. Very good construction. This particular version has a better base and stands very stable. This is because when you try to close it while you're asleep, it doesn't easily fall. The sound it has is very good, not like other alarm clocks that startle you in your sleep. It is very sensitive to touch. When it rings, to stop it, you just need to touch it anywhere. Very convenient, instead of searching for a button. Then with the snooze, it rings again 5 minutes later. It is very easy to operate. For me, it only has one drawback. Because I work shifts, and sometimes I set the alarm clock in the morning, other times in the afternoon, other times in the evening, the problem is that to go from one hour to another, it goes minute by minute, so you are delayed until you reach the desired time. But for someone who always wakes up in the morning, I don't find any drawbacks. Maybe it is the best in its category. It takes one AA battery. I have yet to see what autonomy it will have.
